Vinyl siding outperforms aluminum in nearly every category that matters: cost, maintenance, energy efficiency, and longevity.
Vinyl siding outperforms aluminum in nearly every category that matters: cost, maintenance, energy efficiency, and longevity.
Vinyl has been the number one exterior cladding choice in the U.S. and Canada since 1995. For homeowners evaluating the best siding, the differences are significant enough to make aluminum a difficult choice to recommend.
What Homeowners Should Know
- Maintenance demands: Vinyl only needs mild soap and water for periodic cleaning. Aluminum dents, oxidizes, and eventually needs repainting — costs for exterior painting can reach up to $12,000.
- Energy performance: Insulated vinyl siding can improve a home’s air tightness by an average of 11%. That added performance matters in colder climates where heating costs add up quickly.
- Heating cost savings: In a study of five re-siding projects, insulated vinyl delivered an average energy savings of 5.5%. Aluminum offers no comparable insulation benefit on its own.
- Return on investment: Vinyl siding carries an ROI of 97%, according to the Cost vs. Value Report. That’s a strong return for homeowners comparing composite siding vs vinyl and other upgrade options.
- Fire resistance: Rigid PVC requires 45% oxygen to sustain combustion, which is higher than the 21% found in normal air. Aluminum, by contrast, conducts heat rapidly — a real concern in extreme conditions.
- Color and design: Vinyl comes in a wide range of profiles, textures, and colors without the need to repaint. Aluminum fades and chalks over time, limiting long-term curb appeal.
